Abstract: An adaptable barrier system protects a site of value that is adjacent to a trafficable surface, from impact by a vehicle. The system includes traffic patterns to reduce speed, followed by a first impact element that causes a vehicle to become elevated from the trafficable surface. A bed having a deformable structure or material beyond the first impact element lowers the elevation of a vehicle that encounters the bed. A cover overlies the compressible material to allow passage of pedestrians and lightweight vehicles. An impact element line beyond the bed has sufficient height to impact a chassis of the vehicle having an elevation that is lowered by the bed, and prevent further progress of the vehicle. The combination of the first impact element, the bed and the impact elements line may be reproportioned with respect to each other to provide a barrier intended to suit a particular application.

Abstract: The cable, in particular of the stay cable type, comprises a set of traction reinforcements, two devices for anchoring the reinforcements in two respective zones of the construction, the reinforcements being spaced apart from one another at the anchoring devices, means for deviating the reinforcements in order to cause the reinforcements to converge toward a running part of the cable into a substantially parallel bundle which is more compact than at the anchoring devices, and a guide member which is in closely set contact around the set of reinforcements. This member has an inner surface, the cross section of which is adapted to the peripheral shape of the parallel bundle and the longitudinal section of which has a convex curvature which, over the length of the guide member, allows angular deflections of the reinforcements which are substantially greater than the maximum angle of convergence of the reinforcements between the anchoring device and the running part of the cable.

This pavement uses a binder specially developed to secure the binding between an upper polyurethane chip layer and a lower permeable concrete layer as well as the binding among the waste-polyurethane chips, resulting in excellent strength and durability, and uses recycled polyurethane chips to provide elasticity and permeability suitable for sports activities, walking, and outdoor exercises.

Abstract: A vehicle capture net disposed between a pair of towers each of which includes a shaft, a pair of spools coupled to the shaft, and a pair of straps connected to the net. Each strap is wound on a spool. A brake is coupled to the shaft and to the spools for providing a restraining force of increasing magnitude as the straps are unwound. Unwinding of the straps from the spools advances the pair of spools on threaded portions of the shaft to compress the adjacent braking surfaces against each other. The vehicle is stopped by deploying a vehicle capture net connected to at least one pair of straps each wound on a spool, permitting the vehicle to collide with the capture net and to unwind the straps from corresponding spools, and providing a restraining force of increasing magnitude on the straps as the straps are unwound from the spools.

Abstract: A dozer blade control system controls the position of a bulldozer blade, maintaining the blade at a constant position as the dozer travels through a worksite. The control system monitors the angle of the dozer blade with respect to the earth and when it senses that the dozer blade is tilting, it corrects the dozer blade's position by extending or retracting hydraulic cylinders that couple the dozer blade to the chassis of the crawler-tractor. When the dozer chassis pitches forwards, the blade begins to tilt forward and to drop closer to the ground. The control system senses this forward rotation of the blade and retracts the hydraulic cylinders that couple the blade to the chassis, causing the blade to return to and maintain its original position.

The foldable ramp overcomes the disadvantages of the prior art by providing a ramp having a first ramp section and a second ramp section, pivotable relative to each other between a folded storage position and an open working position wherein the ramp sections are prevented from pivoting to a coplanar position relative to each other in the working position so as to increase load capacity.

Abstract: A cutting head is provided for milling rumble strip depressions in a road surface. The cutting head has a center rotational axis and a transverse diameter that varies along the length of the rotational axis so that an outer cutting surface of the cutting head defines a plane curve, such as an ellipsoid with truncated ends. The cutting head is mounted on a milling machine and rotated about the rotational axis as it is moved alternately up and down into the road surface. As the milling machine moves down the road, the movement of the cutting head creates spaced apart rumble strip depressions in the road. Because of the elliptical configuration of the cutting head cutting surface, the dimensions of the depressions can be varied along both the forward and lateral axes by simply varying the depth of cut. The curved profile of the cutting head along the rotational axis creates rumble strip depressions that avoid the sharp ninety degree corners and vertical side walls found in conventional rumble strips.
